| //! ADBC: Arrow Database Connectivity |
| //! |
| //! ADBC is a set of APIs and libraries for [Arrow](https://arrow.apache.org/)-native |
| //! access to databases. Execute SQL and [Substrait](https://substrait.io/) |
| //! queries, query database catalogs, and more, all using Arrow data to |
| //! eliminate unnecessary data copies, speed up access, and make it more |
| //! convenient to build analytical applications. |
| //! |
| //! Read more about ADBC at <https://arrow.apache.org/adbc/> |
| //! |
| //! This library currently provides: |
| //! - Structs for C-compatible items as defined in [`adbc.h`](https://github.com/apache/arrow-adbc/blob/main/c/include/arrow-adbc/adbc.h). |
| //! - A driver exporter that takes an implementation of the abstract API and |
| //! turns it into an object file that implements the C API. |
| //! |
| //! # Driver Exporter |
| //! |
| //! The driver exporter allows exposing native Rust drivers as C drivers to be |
| //! used by other languages via their own driver manager. Once you have an |
| //! implementation of [adbc_core::Driver], provided that it also implements [Default], you |
| //! can build it as an object file implementing the C API with the |
| //! [export_driver] macro. |
